A numerical study of the stability of U(1) × U(1) × Z2 Dirichlet topological defects (D-walls) has been carried out for a classical scalar field theory. It is found that the D-walls are stable for a wide range of coupling parameters and under perturbations to the wall. However, when two walls are connected by a string, they annihilate via a mechanism analogous to the Langacker-Pi mechanism for monopoles.
